Patent DE-2617964-A1 (DE)
Title: Fertiliser prodn. from sewage sludge - by mixing with unslaked burnt lime
Inventor: DEBBELER BERNHARD
IPC: C02F11/12
Filed: 1976-04-24
Abstract: Process for treatment of sewage sludge comprises mixing the sludge with unslaked, burnt lime (CaO). The treated sludge is useful as a complete fertiliser which does not alter soil pH. Pref. 1 pt. 90-95 % burnt lime per 25-30 pts. sewage sludge is used. The amt. of lime added is sufficient to produce a dry mass. Heat generated during mixing raises the temp. to 80-120 degrees C and this in combination with the caustic action of the lime kills pathogenic bacterial.

Title: Synchronising control system for separate sound and cine recordings - uses reference signal groups and two time constant switching circuits
Inventor: BROEMEL HARTMUT
IPC: G03B31/04
Filed: 1976-09-09
Abstract: The synchronising control for the sound tape and the cine film uses a series of impulses in fixed sets on the sound track. The spacing of the sets corresponds to the frames on the cine film. The frame signals are derived from a sensor on the rotating shutter and a control circuit compares the sound and cine signals to correct the synchronisation. In order to provide accurate stop signals for the tape recorder, two timing circuits are connected in series. One circuit has a time constant greater than the separate impulse lengths and the time constant of the second circuit is greater than the spacing of the sets. A signal on the output from both circuits stops the tape recorder.

Title: Tool slide advance control system - has switches actuated by moving cams mounted on sides with fine and coarse adjustment
Inventor: KRIEGL MAX
IPC: B23Q16/00
Filed: 1977-01-18
Abstract: The control system has moving cams for actuating switches and is for use with machine-tool slides to control the advance and the depth of cut. The system includes an end of run switch whose effective position is related to the distance between the extremity of the slide and the workpiece. This distance can be adjusted by two cam-slides (21, 22) of which the primary (21) has coarse adjustment (23, 24) relative to the machine sub-frame. The second cam slide (22) can be finely adjusted (26) relative to the primary (21). The primary cam-slide (21) constitutes a stop. The slide may be driven by a linear-electro-hydraulic amplifier, and the terminal position may be determined by an electric induction displacement sensor which encounters the stop.

Title: Gas purification filter plant - with gas passing through solid particles flowing countercurrently, in chamber with rakes ensuring uniform flow
Inventor: SGASLIK FRIEDRICH DIPL ING
IPC: B01D46/34
Filed: 1977-02-05
Abstract: A plant for purifying a gas, contg. dust consists of a cylindrical body with pref. several annular filter chambers parallel to one another and one above another. The body has an upper entry and a lower outlet for the solid particles and a lower inlet and upper outlet for the gas. The solid particles flow through ducts in the outer part of the body into the annular chambers and are discharged over bases which slope towards the middle of the chamber, on to horizontal surfaces. Scrapers attached to a vertical shaft pass over the cone of solids formed and remove a predetermined quantity which falls into pockets in a sleeve, and from the sleeve into the bottom of the body where the solids are discharged. The rate of rotation of the shaft determines the flow and discharge of the solids. The gas passes upwards and sideways through the moving bed of solids to a collector from which it goes to the outlet. The plant is partic. useful for removing dust from e.g. air or from residual gas during the mfr. of cement. It ensures a more regular flow of filter medium than in existing plants. The flow can be adapted to the needs of the partic. sepn. being carried out so as to give optimum filtration.

Title: Water cooled reactor with fuel element support - composed of hollow vertical tubes aligned with elements and clamped to form spacing grid
Inventor: REZEPOV VLADIMIR KONSTANTINOVI
IPC: G21C3/12
Filed: 1977-05-27
Abstract: An appts. for supporting and spacing nuclear fuel elements in a water-water reactor comprises a vessel with a perforated bottom, the perforations serving the inlet of the water coolant into the vessel to flow around the elements. The supports for the fuel elements consist of vertical tubes, one tube being located beneath each fuel element; lateral openings in these tubes permit passage of the water coolant to the fuel elements; the upper ends of the tubes are widened out, are in intimate contact with their neighbours and are surrounded by an annular girdle so that they are all bound together to form a spacing grid for the fuel elements. Since there is no separate spacer grid to be mfd., construction is simplified and made more economic. The arrangement is highly reliable in operation.
Patent DE-2727305-A1 (DE)
Title: Rod contg. fine silicon crystals - made by chemical vapour deposition and then zone melted to mfr. monocrystalline silicon rod
Inventor: KASPER ANDREAS
IPC: C01B33/035
Filed: 1977-06-16
Abstract: Fine silicon crystals are deposited onto a heated substrate. The Si is obtd. from a reaction gas mixt. contg. a halosilane and H2 and flowing through a reactor contg. the substrate. The process commences with a high molar ratio (MR) in the reaction gas, a high gas flow, and an optimum deposition temp. (DT). During the process the MR, gas flow and DT are lowered or raised according to a prescribed program. The process pref. starts using MR of SiHCl3/H2 = 0.5 and optimum DT 1100 degrees C. Gas flow is pref. 3000-15,000 l/h. After 10 minutes deposition, the MR is pref. reduced to 0.2 and, when half the desired Si rod dia. has been reached, the DT s reduced by max. 200 degrees C for one hour, and the gas flow reduced to 1/4 with MR increased to 0.5. The step involving a temp. decrease of max. 200 degrees C and redn. in gas flow may be repeated for max. three times. With conventional prodn. of polycrystalline rods, coarse crystals can occur which cause dislocations during subsequent zone melting of the rods to produce monocrystalline rods, e.g. for semiconductor mfr. This problem is avoided.
Patent DE-2728058-A1 (DE)
Title: Machine for stamping identification symbols on steel slabs - uses percussion cylinder to drive marking blocks against slabs
Inventor: MUELLERS KARL-HEINZ
IPC: B44B5/00
Filed: 1977-06-22
Abstract: Identification symbols are marked on steel slabs by means of a machine (1) fitted with a percussion cylinder (12). A number of marking blocks (9), with the required symbols embossed on their ends, are mounted on a rack which forms a circular arc. The rack can be rotated by a worm and wheel drive to bring the required block in line with the hammer head (13) of the percussion cylinder (12). The block (9) is then struck by the hammer head and impresses its symbol on the steel slab. The use of a curved rack to support the marking blocks (9) means that at any given time only one block is in contact with the steel slab and so the machine is not affected by surface irregularities in the material.
Patent DE-2731804-A1 (DE)
Title: Safety unit for liq. gas tanks - uses inert gas source to apply additional pressure onto blowoff valve
Inventor: KOBER DRAGUTIN DIPL ING
IPC: F17C13/12
Filed: 1977-07-14
Abstract: The safety unit esp. for a ships tanks has an auxiliary-controlled blow-off valve. The valve is charged on one side by the gas pressure in the tank, and on the other side by the auxiliary control unit at a pressure which moves the valve out of engagement with the valve seat, when a pre-determined reaction pressure in the tank is exceeded. A unit charges blow-off valve (10) plunger (19) with an additional gas pressure, to press it against the valve seat (17). The unit which is connected to a relief member for the valve plunger, consists of an inert gas source (5a), connected via a back pressure valve (54) or a throttle (55) to the blow-off valve. The auxiliary control unit consists of a pilot valve (30).

Title: Overload release coupling for camera film drive - has two balls between discs on different radii to allow disengagement through full circle before reset
Inventor: GATH FRIEDRICH
IPC: F16D7/08
Filed: 1977-08-01
Abstract: The overload release coupling has two coaxial discs (2, 3), one of which is secured to an axially fixed shaft (1). The other disc is secured to a shaft (4) which is axially spring-loaded (5). Torque between the shafts is transmitted by two balls (7, 8) each situated in a pair of confronting recesses (2a, 3a; 2b, 3b) of the two discs. The balls are 180 deg. apart to distribute the loading on the discs but the balls are situated on different radii. This enables the shafts to remain disengaged for nearly 360 deg. before the balls re-seat after a prior disengagement.
